There are two treatment methods for traditional drilling fluids, one is natural precipitation and the other is chemical precipitation. The former erodes the well wall very seriously and cannot be drilled with sandstone; the latter is mainly treated with soft cement as mud. Alkaline combined mud or cement slurry is currently commonly used + cement slurry, cement slurry + Ca2+H2S+H2O. Commonly used are: cement slurry, hard cement slurry cement slurry (cement emulsified slurry), mud, hydraulic separation agent (solid phase), mud treatment agent, etc. The main purpose is to remove the damage to the formation caused by the harmful substances contained in the hydraulic drilling fluid, and cause damage or even damage to the equipment. Therefore, drilling fluid treatment materials (such as cement, resin, etc.) need to use anti-corrosion and impact resistance properties to treat drilling fluid. Such as oil seal, waterproof gas, mud, etc. Among them, mud is divided into three categories: mud, mud treatment fluid and mud.
